Answer: x=-14

Step-by-step explanation:

Get rid of parentheses: -2x-5-23=0

Add all the numbers together, and all the variables: -2x-28=0

Move all terms containing x to the left, all other terms to the right:

-2x=28

x=28/-2

x=-14

Which of the following would be equivalent to 92 ⋅ 96? 9 to the 8th power over 9 to the 7th power 92 ⋅ 97 9 to the 10th power ov
san4es73 [151]
9^2 × 9^6=9^10/9^2

When multiplying exponents, if the bases are the same you add the exponents.
9^2 × 9^6 = 9^(2+6)=9^8

When dividing exponents, I'd the bases are the same you subtract the bottom exponent from the top.
9^10/9^2=9^(10-2)=9^8

9^8=9^8

Solution: 9^10 over 9^2

What is the correct classification of the system of equations below? 5x + 6y = 1 y = -5x + 6 A. parallel B. coincident C. inters
babymother [125]

Answer: OPTION C.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the system  of equations:

\left \{ {{5x + 6y = 1} \atop {y = -5x + 6}} \right.

Solve for "y" from the first equation in order to write it in Slope-Intercept form:

5x + 6y = 1\\\\6y=-5x+1\\\\y=-\frac{5}{6}x+\frac{1}{6}

Since the lines have different slopes, they cannot be parallel or coincident. Therefore, they are Intersecting.

What is the missing reason in the proof?
laila [671]

It might seem silly, but it's important to say that something is equal to itself. This applies to numbers like saying 2 = 2 and it also applies to geometric lengths as well. In line 5, we say that segment DB is the same length as segment DB. In short, DB is congruent to itself. This property is known as the reflexive property of congruence. You can think of a mirror giving off a reflection which has a similar word structure to reflexive.

You are correct if you were going to select choice B as the answer.

Mary and vivian have some money. if mary gave vivan $8 they would have same amount. However if vivan gives mary $8, then mary wo
kow [346]

Answer:

Money with Mary = $28

Money with Vivan = $12

Step-by-step explanation

Money with Mary = $ m

Money with Vivan = $v

If mary gave vivan $8 they would have same amount. $ 8 is reduced from Mary's amount 'm' and $8 is added  to vivan amount 'v'

m - 8 = v + 8

m = v + 8 +8

m -v = 16     ----------------(I)

If vivan gives mary $8, then mary would have 9 times as much as vivan.

9(v - 8) = m + 8

9v - 72 = m + 8

9v - m = 8 + 72

-m + 9v = 80 --------------(II)

Add equation (I) and (II). Thus m  will be cancelled and we will get the value of v

(I)       m - v  = 16

(II)    <u>-m  + 9v = 80</u> {Now add}

               8v = 96

                 v = 96/8

v = $ 12

Plugin v = 12 in equation (I)

m - 12 = 16

m = 16 +12

m =$ 28
